4, You must call the getHomeData method to get the Home detail information, because only after calling the getHomeData method, the attributes in the home instance object will have data;

5, After the above four steps are correct, perform your operation;

If you use the scene function (especially if you are using the scene business package), you still need to get the scene data before using it.

[self.home getHomeDataWithSuccess:^(ThingSmartHomeModel *homeModel) {
    // Get scene data in advance
    [self loadSceneList];
} failure:^(NSError *error) { }];
- (void)loadSceneList {
    // If the one-touch execution and automation list are empty, call the following method in advance in your code:
    // If the following code is not written, when using the scene business package, there may be a situation where create scene-->add task-->choose existing smart scene-->data is empty
    id<ThingSmartSceneBizProtocol> impl = [[ThingSmartBizCore sharedInstance] serviceOfProtocol:@protocol(ThingSmartSceneBizProtocol)];
    [impl getSceneListWithHomeId:[SRHome getCurrentHome].homeId withSuccess:^(NSArray<ThingSmartSceneModel *> * _Nonnull scenes) { } failure:^(NSError * _Nonnull error) { }];
}
